49.256 Epinotia cinereana (Grey Aspen Bell)
ws: 12-17mm; Jul-Aug; aspen (Populus tremula); status uncertain as previously considered conspecific with E.nisella
Synonym: Evetria cinereana (Pierce & Metcalfe)
Synonym: Evetria cinereana (Pierce & Metcalfe)
Epinotia cinereana §1 male
ID: Similar to E.nisella, generally grey with black streaks, but lacks the solid black or reddish medio-dorsal blotch shown by E.nisella.
Was considered conspecific with E.nisella (form cinereana) by Bradley (BTM) with the comment that there were no genital differences - however genital differences had previously been described by Pierce & Metcalfe who regarded cinereana as a separate species - a status to which it has recently been restored.
Male genitalia: Aedeagus with 18-20 cornuti (40-50 in E.nisella) Pierce and Metcalfe also give a break in the row of spines on the outer edge of the sacculus in E.nisella vs spines continuous in E.cinereana - but this distinction does not seem to be valid.
